is the bearing actually loose in the housing ??,,if so its the wrong bearing, looks like the lower bearing..
some housings are a slight press fit others fall in , there is a snap ring that holds the bearing in place , you,ll see when you replace your housing with the one in your picture.
PET doesnt list the bearing , but this is the one 911-347-771-02,,
here is some good info on the later columns,
